Presenters

Michael Thiele, Claas Wilke (TU Dresden), Editing and Parsing OCL constraints using Dresden OCL and EMFText - Since its first official release in 1997, OCL has been applied as a constraint language to many different modelling and metamodelling languages. During our demo we'd like to present Dresden OCL which allows OCL editing, parsing and interpretation in the context of various modeling languages. Furthermore we plan to demonstrate our OCL interpreter that is able to evaluate OCL constraints on different runtime objects and data as Java objects or XML data.

Mirko Seifert (TU Dresden), Programming-Oriented Modelling - Programming and Modelling are often conceived as two contrary activities. Developers used to solve problems by writing programs in a General Purpose Language (e.g., Java) can hardly imagine that modeling---or Domain-specific Languages---can fully replace source code. Truth is, there is no need to do so. Model-driven and code-centric development can actually complement each other. One can stick with traditional software development that is focused on source code and still replace parts of applications that are more easy to develop using models (or DSLs). The talk will show how to tightly integrate Java programs and EMF-based modeling languages (e.g., built using GMF, Xtext or EMFText). or

Jendrik Johannes (TU Dresden), Model and Code Composition with the Reuseware Composition Framework - The Reuseware Composition Framework is an open-source EMF-based composition tool. Reuseware allows language developers to extend modelling and programming languages to support new kinds of components (e.g., aspects). Language users can then use the tooling offered by Reuseware inside Eclipse in combination with other modelling tools. We demonstrate both the tooling for language developers to quickly add component support to an arbitrary language and the tooling for language users to specify and compose components.
